Just a few reminder before accessing the site: This is a non-Microsoft website. Please see this link bellow, useful information can be seen here to resolve this concern. Please let us work together to find a solution for this concern. I understand that there are concerns encountered so far where a Activate Windows' Watermark is on your screen. I am glad to work with you and help you find a resolution for this concern. Thank you for bringing this concern to us. I'm also unable to install updates to fix this issue as every time I search for updates it continues to show that it's searching for updates for a while.

I'm confused as to why I have two different Product IDs and three different Product Keys, or specifically two with an error saying I've Troubleshooting, searching online for others who've had similar issues and tried all avenues to try and solve this problem. It also says "The last product key you entered can't be used on this copy of Windows." However the product key in this message is not the one I entered (my system), nor is it the one found in Settings. To receive another error code: 0x80070422. I've used the Command Prompt to find my Product Key (which as mentioned is different for some reason) and clicked on 'Change product key', typed in the Product Key, only The Product ID and Product Key are completely different from what appears on my system. When going into Settings > Update & Security > Activation, I get the error code: 0xC00F074. I keep getting the 'Activate Windows' watermark on my laptop, despite having Windows 10 installed.
